This long awaited second edition of this bestseller continues to provide a comprehensive, user friendly, down-to-earth guide to elementary statistics. The book presents a detailed account of the most important procedures for the analysis of data, from the calculation of simple proportions, to a variety of statistical tests, and the use of regression models for modeling of clinical outcomes.

The level of mathematics is kept to a minimum to make the material easily accessible to the novice, and a multitude of illustrative cases are included in every chapter, drawn from the current research literature. The new edition has been completely revised and updated and includes new chapters on basic quantitative methods, measuring survival, measurement scales, diagnostic testing, bayesian methods, meta-analysis and systematic reviews.

'... After years of trying and failing, this is the only book on statistics that i have managed to read and understand' - Naveed Kirmani, Surgical Registrar, South London Healthcare HHS Trust, UK

The second edition of this highly successful, user-friendly book, continues to provide an excellent foundation in statistics for the uninitiated, making it ideal for both students and professionals in health care and medicine who may be either approaching the subject for the first time, or who want to refresh their understanding of any one of a number of statistical concepts and applications.

As with the first edition, the informal and light-hearted style, and the author's avoidance of too much mathematics, makes the material very accessible. The addition of two new chapters, one on survival analysis, the other on systematic review and meta-analysis, significantly improves the coverage offered.

New in this edition:

  • Measuring survival: Kaplan-Meier survival curves; comparing survival in two or more groups.Hazard ratios and the Cox regression model.
  • Systematic review: methods and problems; combining results - meta-analytic methods.

Reviews of first edition:

"His (the author's) work can be highly recommended for health workers, medical students and any other professionals who are revising statistics or approaching it for the first time."
Statistical Methods in Medical Research

"This basic book is exciting and fun to read. Information is presented in a digestable and humorous format. Examples are appropriate to each subject area and easily understood."
Clinical Trials

  • Contains work-through examples, using up-to-date, illustrative data.
  • Gives insightful examples of the use of the SPSS and Minitab statistics
  • programmes for some common applications.
  • Provides lots of exercises to improve understanding and consolidate learning
